Description

Technical Field

[0001] This utility model relates to the field of electric two-wheeled vehicle switch technology, and in particular to an intelligent five-way control switch assembly for electric two-wheeled vehicles. Background Technology

[0002] Electric vehicle handlebars are usually equipped with switch components, which make it convenient for the driver to honk the horn, change gears, switch turn signals and turn lights on and off while driving.

[0003] However, as consumers demand more and more functions from electric vehicles, the number of functions that need to be implemented on electric vehicles is also increasing, which leads to an increase in the number of switches that operate these functions. Currently, most switches on the market control only one function, resulting in a single control method and a large number of switches on the handlebars. Furthermore, existing switches do not have lights, making operation inconvenient in low-light environments and prone to misoperation when there are many switches. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an intelligent five-way control switch assembly for electric two-wheeled vehicles. The five-way control switch can realize multiple functional requirements without the need to install multiple switches, saving space on the handlebars.
